View Rule

The National Marine Fisheries Service proposes to require federally permitted Hawaii deep-set longline vessels that utilize stern setting to employ a tori line (bird scaring streamer) system instead of currently required blue-dyed bait and strategic offal discharge (fish, fish parts, or spent bait) to mitigate seabird interactions when fishing north of 23° N. The proposed action is intended to reduce albatross interactions while also streamlining fishing operations and management of the fishery. Recent research demonstrated that when tori lines are employed in lieu of blue-dyed bait and strategic offal discharge, albatross attempts are 1.5 times less likely, contacts are 4 times less likely, and captures 14 times less likely. The Western Pacific Fishery Management Council recommended this proposed action to address increased albatross interactions in the deep-set fishery since 2015 and the time and cost of existing seabird mitigation measures. The Hawaii longline fishery is a limited entry fishery with a cap of 164 vessels. In 2020, 146 of these vessels actively fished using deep-set longline gear. The action would likely result in minor economic impacts. By removing the blue-dyed bait requirement for stern-setting deep-set long vessels operating north of 23° N, each vessel would save $333.93 on average each year. Requiring the use of tori lines (one tori pole and two tori lines) would result in an upfront cost of $1,075 per vessel, however, the tori pole is expected to last many years, while each of the tori lines is expected to last several years. Given the durability of the required new gear, the annual cost per vessel is likely to be about the same or less than what fishermen are now spending on blue dye. Other features of the action would serve to reduce operational burden on the fishermen.
